MACHINE FOR MANUFACTURING BACKING.

SPECIFICATION forming part of Letters Patent No. 647,056, dated April10, 1900.

Application filed June 5, l 8 9 9 To all whom it may concern:

Be it known that I, FRANK-O. \VARD; a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented certain new and useful Improvements in Machines for theManufacture of Backing; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to figuresof reference marked thereon, which form a part of this specification.

This invention relates to a machine for the manufacture of backing.

It has been the practice for many years to manufacture what is known inthe trade as backing. This consists of a number of thin slats or stripsof wood, which are glued between two sheets of paper, thus forming asingle board from the several laminations of wood,which will not warp orbecome displaced. My present invention relates to a machine for themanufacture of this class of antiwarping backing. Its'object is toproduce a machine for the purposes as above outlined, with which largequantities of backing maybe manufactured in a comparatively-short time,is practically automatic in its operation, simple in its construction,and in which the several laminations of wood or slate are so fed andsecured between the paper as to produce a stiff antiwarping backing.

To that end it consists, first, in the arrangement for feeding the slatsto the machine; second, in the manner of spreading the slats evenly upona plane, and, third, in means for feeding the slats between the gluedpaper, 'so as to form a firm board when completed.

The invention further consists in the details of its construction andcombinations of its operative parts, all of which I will now proceed todescribe more definitely and then point out in the claim that which Ibelieve to be novel.

In the drawings, Figure 1 is a View showing the general arrangement ofmy improved machine. Fig. 2 is an enlarged side elevation of the machinewith the communicating gearing removed. Fig. 3 is a longitudinal sectionFig. 4 is a top plan taken in side elevation.

Serial in; 719,383. on) model.)

View with the slat-receiving rolls and belts removed, Fig. 5 is a frontface view of the machine; Figs, 6 and 7 are detail views of the endlessbelts for feeding the slats to the machine, and Fig. 8 is a detail viewof one of the guides employed for retaining theslats' in a horizontalposition.

Referring to the drawings, 1 is the frame of the machine, to the sidesof which are secured the hangers 2 and 3. In these hangers 2 and 3 aremounted the several communicating shafts, the shaft 4 being mounted-inthe lower end of the hangers 2 at the forward end of the machine andjournaled in the boxes 5 and may be adjusted vertically by theadjusting-screws 6. In the upper ends of the hangers 2 are looselymounted the shafts 7 and 8, upon which the pulley-wheels 9 are rigidlymounted. Stationary plates 10 are arranged on each side of thepulley-wheels 9.

These plates 10 are loosely mounted on the shafts 7 and 8 and extenddown to and engage the cross-bars 12and 26 at their lower ends, thuscausing them to be held in a vertical position. At the upper ends of theplates 10 are mounted the adjustable pulley-wheels 13, which communicatewith thepulley-wheels 9 through the endless belts 15, the pulleys 13being adjustable vertically by the adj ustingscrews 16, so as to take upany slack in the belts 15. There are two sets of. pulleys 9 and 13, withbelts 15 on each of the shafts 7 and 8, and the slats are fed into themachine between these belts 15, as will be hereinafter described. Withinthe loops of the belts l5 and movably secured between the stationaryplates 10 are the spring-pressed shoes 17,'the springs 11 holding theshoes against the belts 15, which are in turn pressed against the slats18, resting between them, a detail of which is shown in Figs. 6 and 7.

19 19 are two vertical arms extending from the brackets 2. These arms 19are on a line between the belts 15 and are the ends to the receptaclethus formed to receive the slats 15. In making backing of a given widthit is de sirable to use slats out just as long as the width of boarddesired. To retain these slats in alinement when placed between thebelts 15, I have provided the vertical gage plates or strips 20, havingthe horizontal pins 21, adj ust-ably secured in the arms 19 of thebrackets 2 by the set-screws 2%. The slats when placed between the beltsrest upon cross-strips 22 and over the toothed feedingwheels 23, thetoothed feeding-wheels 23 being so adjusted in the bearings 5 as to havetheir teeth engage the lower slat only of the stack resting between thebelts 15, and as the toothed Wheels 23 are revolved in the directionindicated by the arrow the slat is carried from under the stack and ispushed between the guides 22 and 25, the lower guides 22 runningparallel with the machine, forming a bed which receives the slats fromthe stack as they are successively fed to it by the toothed wheel 23 andthe adjustable guides 25, which are secured to the cross-rods 26 and 27and are rigidly held in place by the nuts 28, just sufficient spacebeingleft between the guides 22 and guides to permit the slats to passloosely between them, as shown in the drawings. As the slats are carriedfrom the stack and between the guides 22 and 25 they pass between thefeed-wheels 29 and 30, mounted in the hangers 3. As many of these wheels29 and 30 may be used as desired, and these are mounted parallel withthe slats 18 passing between them, and as they engage each slat theyforce it forward to the depression-rollers 31 and 32. Thesedepressionrollers 31 and 32 are mounted directly over each other,similar to the feeding-wheels 29 and 30, and the paper sheeting 33 and34, which is to be glued to the backing, is fed to the machine overthese rollers 31 and 32, the pressure-rollers causing the paper tofirmly adhere to the slats. In operation, 35 are reservoirs for holdingthe liquid glue, in which are mounted the supply-rollers 36. 33 and 34are the paper sheetings, which are spread with glue as they pass overthe supply-rollers 36, (see Fig. 1,) from whence the paper passes overguide-ro11ers,as seen in the drawings, and to the depression-rollers 31and 32.

The slats 18 are fed into the machine between the belts 15, as abovedescribed, and stacked over the toothed feeding-wheels 23, where theyare successively carried between the guides 22 and 25, and passingbetween the feed-wheels 29 and 30, where they are forced forward to thedepression-rollers 31 and 32. These rollers 31 and 32, over which theglued paper passes, are loosely mounted in the hangers 3 and are causedto revolve by the slats 18 being forced between them, thus causing theslats to press closely against each other as they are forced along bythe wheels 29 and 30, and the glued paper sheeting 33 and 34, which isnow pressed upon the slats as they pass between the rollers 31 and 32,holds the slats firmly in place, thus forming a stilt antiwarpingbacking.

It is found in practice that a slightly-milled surface given to theWheels 29 and 30 and a coating of vulcanized rubber 38 given to therollers 31 and 32 greatly adds to the elfectiveness of the machine, andthis construction is preferred,

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

In a machine for the manufacture of lan1inated backing, a plurality ofendless belts mounted within a frame and arranged to exert a downwardpressure upon a stack of slats placed between them, toothedfeedingwheels mounted beneath said slats and adapted to successivelyengage the lower slat, and carry it upon the bed of the machine, a series of secondary feeding-wheels adapted to press the slats closelytogether upon the bed and force them between depression-rollers, saiddepression-rollers being arranged to exert a pressure upon glue-coatedpaper fed over them and adhered to each side of the slats as they passbetween the depression-rollers, substantially as shown and described.

In testimony whereof I have signed my name to this application in thepresence of two subscribing witnesses.

FRANK O. WARD.
